How to use this course / term average calculator
Combine coursework categories into a term average with visible contributions. Enter a category percentage and weight, or switch to equal entries for equally weighted assignments. The calculation normalizes the supplied weights and shows how each category contributes to the overall result.
- Enter the category percentage values in the labeled fields, using consistent units.
- Choose the input method that matches your records. Switching methods loads a labeled example so you can see the required structure.
- Select Calculate and check the result alongside its working. Reset starts a fresh calculation.
Course / Term Average formula
Term average = Σ(category score × category weight) ÷ total weight
Calculate each category’s own percentage first, then enter it once with its category weight. Listing the assignments again alongside their category mean would count the same work twice.
Follow the numbers
Coursework at 75 with weight 30 and exams at 85 with weight 70 give (2,250 + 5,950) ÷ 100 = 82.
Load the example above to inspect the entries, then change one value and calculate again. The result follows your selected method. Display rounding changes how the answer is shown; it does not change the underlying observations or weights.
What to check before using the result
If you enter only completed categories, this is an average of those categories, not a prediction for unfinished work.
Keep enough precision in the source values for your task. A result calculated from rounded summaries can only be as precise as those summaries. If a number was mistyped or an observation is missing, correct the inputs and calculate again before copying or exporting the answer.

Common mistakes to avoid
- Confusing a blank with zero. A real zero is an observation. Missing information is not automatically zero.
- Mixing incompatible scales. Use consistent units, or normalize values before combining them.
- Rounding too early. Keep the original values and round at the result stage.
- Using the wrong weighting. If you enter only completed categories, this is an average of those categories, not a prediction for unfinished work.
Frequently asked questions
What formula does this calculator use?
Term average = Σ(category score × category weight) ÷ total weight. Coursework at 75 with weight 30 and exams at 85 with weight 70 give (2,250 + 5,950) ÷ 100 = 82.
What should I check about the method?
If you enter only completed categories, this is an average of those categories, not a prediction for unfinished work.
How many entries can I use?
Paste up to 10,000 values, or use up to 100 individual rows when the chosen input method supports them. Numbers must be finite and no greater than 1 trillion in magnitude. Group and old-count inputs have additional whole-number requirements.
Are the displayed decimals exact?
The calculation uses standard floating-point numbers and compensated addition. Results are rounded only for display. Very small values use scientific notation so they do not silently appear as zero. Select the display precision you need, while respecting the accuracy of your original data.
Are my entries saved or sent anywhere?
The calculator performs its arithmetic in your browser. It does not automatically store entries or send them to a server. Copy, print, and CSV actions happen only when you choose them.
